Human Interleukin 2 (IL-2), also known as T cell growth factor (TCGF), is a member of the common gamma chain (γc) cytokine family. The 153 amino acid (aa) human IL-2 precursor contains a 20 aa signal sequence and a 133 aa mature region with one O-linked glycosylation site at Thr3, plus three cysteines, two of which form an intrachain disulfide bond that is essential for IL-2 bioactivity. Mouse IL-2 cDNA encodes a 169 amino acid (aa) precursor containing a 20 aa signal sequence and a 149 aa mature chain. Human IL-2 shares approximately 60% sequence identity with mouse IL-2. To some extent, mouse and human IL-2 exhibit species cross-reactivity. IL-2 is expressed and secreted on γδT cells, activated conventional CD4+ and CD8+ T cells, neurons, microglia, and hematopoietic stem cells in humans.

IL-2 first binds to IL-2 receptor α (IL-2Rα)/ CD25 in the binary receptor complex then recruits IL-2Rβ/CD122 and IL-2Rγ/CD132 to trigger a variety of biological processes. IL-2 plays a key role in the development, maintenance and function of regulatory T cells and in promoting the development of activated CD8+ T cells into memory cells.
